Subungual exostosis (SE) is an uncommon osteocartilaginous tumor. Classic dermoscopic features of SE include vascular ectasia, hyperkeratosis, onycholysis, and ulceration. In this case, a 9-year-old boy presented SE showing a dermoscopic mesh dilated blood vessel pattern surrounded by a scar-like peripheral ring, which represents a novel finding in the medical literature.
